Pardon my ignorance, but what's Derola? A Google search comes up with two of your posts, and a ton of stuff about a Polish artist.

Detrola with a T was a company that built radios

Thanks. I missed "T". Sorry
Detrola is a radio navigation device allowing you to find a radio beacon.

It was compatible only with beacons in continental US, however, so it has no place in DCS (unless we get WWII version of Nevada in the future 😉 ) That's why it never got fully implemented in our Mustang.

Oil dilution, on the other hand, we need that one for sure!

For what? Pilot should do it at the very end of his flight just before the engine stop. For successful start after long cold night for example. But immediately before start after long cold night it doesn't make sense, IMHO...

I know that, but because of lack of persistent state simulation devs made a realism compromise in Mustang and we can use the dilution to lower the oil pressure and warm up the cold-started engine faster. Since we don't have "engine pre-heated by mechanics" option  (like in Il-2GB) either, doing it saves tons of time in missions set with low ambient temp.

Thus, functional diluter (even in such semi-realistic form) would be very handy in P-47, which requires quite a long time to warm up in winter missions.

The Detrola receiver itself is functional in DCS. For both, the Mustang and the Thunderbolt, or it was.

I think it was introduced with Mosquito.

 

It is (was) practicable only on modern maps with ILS systems which serve as a A-N beacons, somehow...
The detrola must by tuned in way that for example 110MHz ILS frequency is tuned as 210kHz on Detrola.

 

Recently i was able to do it on Marianas map.

I believe the rule for manual tuning is to multiply the ILS freq. by two for the Detrola radio scale, so 220 in your example.

You can also set it in the mission editor -- on the radio settings, set the BC-1206 Initial Frequency to the ILS frequency in MHz (110.0 in your example).

@saburo_cz Didn't know about its implementation with Mossie, thanks for the heads-up. So it might indeed be working on Marianas at least.

Never had set up anything ILS related in mission editor (I don't own ILS equipped modules), but will try to understand what you guys are talking about and test it in the free time 🙂 .

Just only one note.

ILS systems in DCS do not transmit A and N in morse code. They only transmit DOT and DASH like LORENZ blind landing system did.

So, DETROLA receives only dot, dash or solid tone, depends on your position to landing centreline.

Mosquito has LORENZ blind landing system receiver, R.I. compass, and it cooperate with modern ILS system in DCS. (Not IRL of course, but in DCS W does)

Detrola was a radio manufacturing company based in Detroit, Michigan, USA from 1931 to 1948.  They made some radios for the US military during WWII.  That explains the "Detrola" box in the P-47D and P-51D in DCS.  It is a Low Frequency Radio Range navigation system receiver of lightweight, compact, vacuum-tube design.

For the explanation of the Low Frequency Radio Range navigation system, I refer you to this Wikipedia page.  I think it explains it very well.

Low-frequency radio range - Wikipedia

It's actually pretty cool.  But not a navigation method we'd like to use in DCS...I'm pretty sure of that. 🙂  There are sample audio recordings of one such navigational aid on the Wikipedia page.  I'm pretty sure you will understand why NDB, VOR, TACAN and ILS took its place.

That said, maybe someone could make a mod to replicate these stations on the Nevada map (or where we could place stations on any map in ME).  As we can currently place transmitters on ground vehicles in DCS, using the Perform Command (Set Frequency and Transmit Message) in Mission Editor, setting frequency, power and assigning an audio file to be played; there might be a way for modders to incorporate the Low Frequency Radio navigation system into that.  I think it would be just for vintage aviation fun.  Probably any radio receiver in any aircraft could be used, but the Detrola in the P-47 and P-51 was specifically for that.  So, as far as I can tell, the Detrola has no practical purpose in DCS.  I thought it might be useable as a voice broadcast receiver, but it doesn't seem to receive voice transmissions of transmitters set up in Mission Editor (doesn't play the audio file).  Only some Morse code station identifier signals of some radio transmitters around the 208-212 kHz range that don't seem to correlate to the 200-400 kHz band.  

DCS REQUEST

A request of DCS would be to make the Detrola radio able to receive radio stations from 200 to 400 kHz and play their audio.  This way we could at least use it as an audio file message/music receiver.  And someone might be able to create a mod to make it function as a Low Frequency Radio Range navigation receiver.

Going from memory right now, I seem to remember that the Detrola BC-1206 reciver was only used for trg in the US as airfields were equipped with the appropriate transmitters.  They were intended to be removed from aircraft before being sent to Europe so we should not have one in the P-47.

Link below corroborates my recollection.
